    MI: Fix printing of frame architecture with Python frame filters enabled
    
    Commit 6d52907e226a (MI: Print frame architecture when printing frames
    on an MI channel) added frame's architecture to MI frame output. However
    the frame architecture was not correctly printed in the output of
    "-stack-list-frames" with frame filters enabled (via "-enable-frame-filters").
    This was because with frame filters enabled, the actual frame printing is
    done in "py_print_frame" rather than "print_frame". This issue is now fixed.
